"double" texas grill???

I was given 2 new, unlined 55 gallon drums. I already have a uds, so i thought I'd make a Texas grill style offset w/ one of these.

Then I thought, why not place them open end to open end, weld them together, and make a double one? Firebox would go underneath, rather than offset on one end. Exhaust stack on each end.

Anybody seen such a creature before? Any reason why it wouldn't work?

Thanks guys.

Anybody have any idea what size my firebox would need to be, and how big the opening should be to the cooking chamber, and how big the exhaust should be (1 on each end)? I've seen a calculator floating around, but I'm not sure if it would be good on this small scale.

Interesting idea, Sean. I'd like to see how it turns out.

I was playing around with a smoker calculator and it looks like I might be able to use a 30 gallon drum for the firebox. It works out to be about 30% of the volume of the cooking chamber, a little short of the recommended 1/3. This should be close enough, shouldn't it? Should I go bigger?

I was gonna use one of those stove kits for the door and 6" damper. Going by what the calculator says though, I f I use 6" openings, I'd need 2.49 of them. I would've thought 2 would be more than enough. Does this sound right? I didn't want to run anything bigger between the firebox & cooking chamber.
